Abstract :
This paper proposes a new approach to disturbance estimation based on a curvature model that improves the disturbance rejection performance of a servo system. The main feature is that the stability of the control system is guaranteed when the disturbance estimate is incorporated directly into the designed servo control law. Experimental results show that disturbances are rejected efficiently when this approach is used.
